Hey Jim, Does this knock happen right after you change the oil? ,, or does it wait a few days to start knocking again.... I have the same issue,,, its the engine getting old.. too much clearance..piston to wall... bearings....??.. I use a half bottle Lucas Oil treatment with each oil change... I put it in last... while the engine is running so it mixes well..and I usually overfill it just a tiny bit...

Local oil change shop did 20% overfill on 2.0L engine... Now nothing but problems. Engine spewed oil everywhere. Couldn't find any leaks. Now overheated x1, and low bass-like sound. (Fried?)


Few engines of my experience would be damaged by only a 20% overfill. The capacity of a typical 2.0 litre engine is around 5 litres so a 20% overfill would make only 1 litre above maximum.
As the engine would be designed to have additional oil pan capacity and probably be baffled to cope with oil swill during cornering and braking, while an extra 1 litre MIGHT make a bit of a mess it would be unlikely to have any lasting adverse effect unless it entered the intake via the breather system when it could seriously shorten the life of the oxygen sensor and CAT.

Lots of folk have topped up their oil without reference to the dipstick and raised the level by far more than your own without ill effect...
Lots of folk have topped up their oil and forgotten to replace the oil cap and had oil spewed everywhere but after a good wash down, an oil top up and a new cap the problem is ended.

We once had an apprentice who was told to fill an engine with oil and he did, literally and to the very top. It started and ran for a short time but sustained no damage.

The obvious conclusion is they actually overfilled the engine by a great deal more than 20% and/or they perhaps caused another problem and/or the law of sod conspired with events and you are a victim of coincidence.

An engine must be carefully washed down in order to have a fighting chance to locate an oil leak but then any leak should become fairly obvious. While the low bass-sound is the typical sound of an engine without an oil filler or with an open or detached crankcase breather, I can think of no connection between the overfill and any resulting mess and the overheating.

If you paid a repair shop to perform a service, you made a contract with them. If the service wasn't performed satisfactorily they are in breach of their contract with you. You should return the car to them and tell them to put it right free of charge. A respectable repair shop would be pleased to do that.

What happens when you overfill engine with oil


Depends upon how much you overfill it. Normally an extra half-quart is no big deal. You'll see it show overfull on the dipstick after you run the engine and then recheck it, but no harm done. Add more than a quart extra and you can get what is known as foaming. The oil in the pan will be churned up by the crank shaft and become aerated. This can reduce oil pressure, lubrication quality, and flow rate. Engine damage can result from this.

My Ford KA, oftenly has the air filter wet with oil,and the oil drips down to the ground.i have tried to take it to the mechanics and this hasn't helped.Please help,what should i do?


This can happen because the oil breather valve (or positive crankase valve) is not working properly. It can also happen if the engine has too much oil (overfilled).

What happens to a car if there is a little too much oil in it? why is it bad for it.


Hi:
A little bit of overfill isn't that bad, but If you put in way too much oil, the engine's crankshaft can actually come in contact with the oil. And because the crankshaft is turning at several thousand revolutions per minute, it can quickly whip your oil into a froth and your engine's oil pump can't pump froth very well, and as a result, it can't get oil to the parts of the engine that need lubrication, and then bad things can happen, sort of like not having enough oil in your engine....

I changed the oil on my 2008 nissan sentra 2.0


You should use the viscosity oil recommended in your owner's manual. Using a heavier weight oil can affect your fuel economy. If you overfilled the engine with oil, drain out a quart. Overfilling with oil will cause the oil to 'foam', and if this happens, you are not getting proper lubrication of components, which can result in damage to your engine.

Blowing oil and smoke


When overfilled, how long before the level was drained back to normal, or was it? The problem with overfilling, is that the oil will 'foam' and not lubricate properly. This can result in serious engine damage. So, make sure it's at the proper level now, if it is, I believe the engine was damaged due to lack of proper lubrication. Wish I had better news. Good luck.

Mercedes SLK230 overfilling oil warning


5.6 liters here in the UK, could be a faulty sensor but try the oil first, easy enough to drain, jack up the rear passenger side so it gets all the oil out when draining.

I have a 2004 Toyata Highlander that occasionally gets an oil overfill from the dealership. On the dipstick (after the car has been running) marks halfway between the full mark and the double cutouts...


Check the oil with the engine warm & off. An accidental overfill of 1/2 quart will not hurt the engine. BUT, 2-3 quarts overfull will result in issues, and I would recommend draining that overfill out. But, 1/2 quart is really nothing to worry about.
